%X The lack of flood measurement data due to complex and changeable landform brings about many inconveniences to hydro-project construction in southwest China. According to data of design flood peak discharge (<i>Q<sub>p</sub></i>) and collecting area (<i>F</i>) at 66 hydrologic stations in 11 basins in the southwest region of China, the relationship between<i> Q<sub>p</sub></i><sub> </sub>and <i>F</i> is researched by statistical analysis. Results show the <i>Q<sub>p</sub>-F </i>relationships in the Jialing River basin, Tuojiang River basin, Fujiang River basin, Minjiang River basin and Lancang River basin follow linear relationship; while in the Dadu River basin, Qingyi River basin and Yalong River basin, the <i>Q<sub>p</sub>-F</i> relationships match well with exponential relationship; and in the Jinsha River basin, Nujiang River basin and Yarlung Zangpo River basin the relationships conform well to power function. The research results offer reference for obtaining the<i> Q<sub>p</sub>-F</i> relationships in ungauged river basins.
